摘 要:目的探讨新辅助化疗后淋巴结癌残留的激素受体阴性乳腺癌辅助化疗方案的选择对生存的影响。方法回顾性分析北京大学肿瘤医院乳腺癌预防治疗中心2002年1月至2012年12月收治的激素受体阴性且腋窝淋巴结转移的原发性乳腺癌病例。其中完成了4~8个周期新辅助化疗以及包含淋巴结清扫的乳腺癌根治性手术,术后病理证实仍有淋巴结癌残留的患者共110例。根据术后有无辅助化疗分为A组(辅助化疗组)和B组(无辅助化疗组)。结果全部患者均为女性,中位发病年龄54.5岁(IQR:47—59岁)。无事件中位随访时间61个月(IQR:51—88个月)。A组82例(74.5%),5年无病生存(DFS)率76.2%(95%CI:66.8%~85.6%)、无远位转移生存(DDFS)率78.9%(95%CI:69.5%~88.3%)、总生存(Os)率81.O%(95%CI:72.4%~89.6%);B组28例(25.5%),5年DFS率57.6%(95%凹:38.6%~76.6%)、DDFS率60.4%(95% CI:41.2%~79.6%)、OS率60.0%(95% CI:40.6%-69.4%)。多因素分析显示,B组发生远处转移的风险为A组的5.256倍(95%CI:1.14—24.17),P=0.033;死亡风险为A组的7.478倍(95%CI:1.58~35.30),P=0.011。结论新辅助化疗后腋窝阳性淋巴结癌残留的受体阴性乳腺癌患者,可能从术后辅助化疗中获益。Objective To explore the influence of adjuvant chemotherapy on the prognosis of hormone receptor negative breast cancer with residual lymph node disease (RLND)after neoadjuvant chemotherapy. Methods A total of 110 hormone receptor negative breast cancer patients treated with 4 - 8 cycles of neoadjuvant chemotherapy were respectively analysed between 2002 and 2012. Residual lymph node disease was comfirmed by subsequent radical mastectomy. Then all these patients were classified into two groups: patients treated with adjuvant chemotherapy (group A ) and patients untreated with adjuvant chemotherapy( group B). Results All patients were female, the median age was 54. 5 years old (IQR :47 - 59 years). The median follow-up time was 61 months( IQR:51 -88 months). There were 82 patients (74. 5% ) in group A, and 28 patients (25.5%) in group B. The five-year disease-free survival (DFS) rate was 76. 2% in group A and 57.6% in group B. The distant disease-free survival (DDFS) rate was 78.9% in group A and 60. 4% in group B. Overall survival (OS) rate was 81.0% in group A and 60. 0% in group B. Multivariate analysis showed that there were significant differences for DDFS rate ( group A vs group B, P = O. 033; hazard ratio [ HR ], 5. 256; 95% confidence interval [ 95% CI], 1.14 -24. 17 ) and OSrates (group A vs group B,P =0.011; HR, 7. 478; 95% CI, 1.58 -35.30) between two groups. Conclusion The patients who have hormone receptor negative breast cancer with RLND after neoadjuvant chemotherapy, may benefit from postoperative adjuvant chemotherapy.
